Background:
Laparoscopic segmentectomy, which maximizes the preservation of the functional hepatic reserve and the possibility for future repeat hepatectomy while ensuring adequate surgical margin, is a feasible alternative to hemihepatectomy for hepatocellular carcinoma (HCC) (Vigano et al. in Ann Surg 270(5):842-851, 2019, Ishizawa et al. in Ann Surg 256(6):959-964, 2012). Herein, we present a video of laparoscopic segmentectomy IV for HCC using hepatic round ligament approach combined with fluorescent negative staining method.
Patient And Methods:
A 44-year-old male with history of chronic hepatitis B virus (HBV) infection for 22 months was referred for treatment of a single HCC in segment IV. The procedure was performed according to the following steps: (1) lowering the hilar plate based on Laennec's capsule (Sugioka et al. in J Hepatobiliary Pancreat Sci 24(1):17-23, 2017) after cholecystectomy; (2) cutting the Glisson's pedicles to segment IV along the fissure for the round ligament; (3) the first parenchyma transection was along the falciform ligament, while cutting some deep pedicles to segment IV; (4) clamping the left Glisson's pedicle and using fluorescent negative staining method (Abo et al. in Eur J Surg Oncol 41(2):257-264, 2015, Funamizu et al. in J Hepatobiliary Pancreat Sci, 2021, Xu et al. in Surg Endosc 34(10):4683-4691, 2020); (5) the second parenchyma transection was performed along the boundary of negative fluorescence region to expose the middle hepatic vein (MHV) using a combination of cranial and caudal approaches.
Results:
The operative time was 190 min, and blood loss during operation was 80 mL. The histopathologic examination showed a solitary HCC, 2.5 cm in diameter, with negative surgical margin and no microvascular invasion. The patient had an uneventful postoperative recovery and was discharged on postoperative day 5.
Conclusion:
The round ligament approach combined with fluorescent negative staining method for laparoscopic anatomic segmentectomy IV is a feasible and effective technique.
